MAC DELEGATING - WILL COMPTURE BREACK?

Hello! I have started yesterday to put a first toe in the water and delegating my first 117 ADAs on a pool called HDLA(w/the cardano ticker instead of that “A”). My Q. is will my MacBook Air support this in the long term?
Also, can I close the comptuter or the app and will it still work if it’s closed?
Maybe these are stupid questions but I’m a newby here…
Thanks:D

Yes, u can close the wallet also, ADA will stay delegated till ur next wallet action
